If your child's playroom has big windows with a lot of light streaming in, then you can use the space around the windows as space for storage. If you are good at woodworking, then you can create shelves yourself or get your neighborhood carpenter to make shelves for you. Keep those toys that are used most often on the lower shelves and keep things that your kids hardly use on the shelves that are higher up. Paint the wall on which the shelves are attached in colorful colors and extend these colors to the shelves as well. You can also match the theme that you are using to decorate the room.

If you are yearning to experiment with more funky colors and yet don't want to overdo it, then blue is the most safest option you have got. Pair the baby blue color with white, a typical bedroom is what you get. Sprucing the decor with some black and other shades of blue is what you need to add some style to the walls. Bold blues are excellent choice to contemporary bedrooms for modern girls. Blue is one color which will always remain in fashion as there are too many different types of shades to choose from. This color is apt for girl's bedroom as it is soft and at the same time eye-catching.

An interesting idea is to paint some "games" on the wall and the floor. You can create a hopscotch game on one of the floor corners and a dartboard on the walls. The kids will love playing these in their spare time. Creating textures on the wall by using techniques like "sponging" will give it a unique look. You can consider painting some of the things that your child likes on the walls to make them interesting for him, such as airplanes, cars, butterflies, flowers, fairies, mountains, oceans, and the like.
